Description

Technical Field

[0001] This utility model relates to the field of pump station technology, specifically a pump station structure for water conservancy projects. Background Technology

[0002] A pumping station is a device and engineering project that can provide hydraulic and pneumatic power with a certain pressure and flow rate. Pumps and pumping station projects are collectively referred to as the water intake, water outlet, pump house and other buildings of irrigation and drainage pumping stations. A pumping station is a complex of electromechanical equipment and building facilities that pump water from a low place to a high place.

[0003] In existing technologies, when a water pumping station draws water, the mud, sand and impurities in the water are also drawn into the pumping station. After sedimentation, they tend to accumulate at the bottom of the pumping station, forming silt. If not treated for a long time, this silt can easily clog the water pump and also emit a foul odor, affecting its working environment.

[0004] Chinese patent discloses a water conservancy pumping station with dredging function (authorization announcement number CN222083666U). This patented technology uses a structure of dredging plate, hard brush and scraper to facilitate the stirring of silt accumulated at the bottom of the pumping station body. The hard brush can remove silt with strong adhesion, while the scraper can easily clean the residual silt on the bottom periphery during rotation, improving the cleaning effect of the device, avoiding affecting the operation of the water pump and preventing the generation of odor.

[0005] However, it has certain drawbacks: during long-term operation, the hard brush and scraper are prone to wear due to continuous friction, which reduces their adhesion to the inner wall or bottom of the pump station body, significantly reducing cleaning efficiency. The worn sludge cleaning components cannot effectively remove adhesive sludge, which can easily cause sludge to accumulate and harden at the bottom. This not only affects the normal pumping efficiency of the water pump, but may also cause blockages, water quality deterioration, and odor problems. Frequent manual shutdowns are required to check, adjust, or replace the sludge cleaning components, which not only increases maintenance costs but also affects the continuity of pump station operation. Utility Model Content

[0006] The purpose of this utility model is to provide a pumping station structure for water conservancy projects to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A water conservancy engineering pump station structure includes a pump station body and a top cover fixed to the upper end of the pump station body. An inlet connector communicating with the interior is fixed to the upper left side surface of the pump station body, and an outlet connector communicating with the interior is fixed to the lower right side surface of the pump station body. A conveying mechanism is provided at the right end of the outlet connector, and a sewage discharge connector communicating with the interior is fixed to the lower left side surface of the pump station body.

[0009] A transparent window is fixedly connected to the lower end of the front surface of the main body of the pump station. A cleaning mechanism is provided inside the main body of the pump station and on the upper surface of the top cover. The cleaning mechanism includes a motor, a connecting rod fixedly connected to the output end of the motor, a connecting plate fixedly connected to the lower end of the connecting rod, a motor fixedly connected to the left end of the upper surface of the connecting plate, a threaded rod fixedly connected to the output end of the motor, a connecting plate connected to the external thread of the threaded rod, a limit rod movably connected to the inside of the connecting plate located on the right side of the threaded rod, and a connecting rod fixedly connected to the right end of the lower surface of the connecting plate, with a cleaning component provided at the lower end of the connecting rod.

[0010] As a further embodiment of this utility model: the conveying mechanism includes a water pump, and the inlet and outlet ends of the water pump are respectively fixedly connected to a water pipe one and a water pipe two.

[0011] As a further embodiment of this utility model: the cleaning component includes a brush, a slider is fixedly connected to the upper surface of the brush, and sliding rods are movably connected to both the upper and lower sides of the slider. A scraper is fixedly connected to the right end of the two sliding rods, and a spring is movably sleeved between the slider and the scraper on the outside of the upper sliding rod.

[0012] As a further embodiment of this utility model: the motor is fixed to the upper surface of the top cover, the upper end of the limiting rod is fixed to the lower surface of the connecting plate, and the axes of the connecting rod and the connecting rod are located on the same vertical line.

[0013] As a further improvement of this utility model: the left end of the water pipe is fixedly connected to the right end of the water outlet connector.

[0014] As a further embodiment of this utility model: the lower end of the connecting rod 2 is fixed to the left end of the upper surface of the brush, the brush is movably attached to the lower inner surface of the pump station body, the scraper is movably attached to the inner side of the pump station body, one end of the spring is fixed to the slider, and the other end of the spring is fixed to the scraper.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes the coordinated action of the brush and scraper in the cleaning mechanism, along with the linkage adjustment mechanism of the second motor, threaded rod, and connecting plate, to automatically compensate for the height of the brush after wear, ensuring it always fits tightly against the bottom surface inside the pump station body. The scraper, under the action of a spring, always fits tightly against the inner periphery of the pump station body. Simultaneously, a transparent window monitors the status of the cleaning components in real time, achieving significant advantages such as stable sludge cleaning effect, adaptive wear adjustment, and eliminating the need for frequent replacement of cleaning components. This greatly reduces the frequency of manual maintenance and operating costs, ensuring the long-term efficient operation of the pump station. Attached Figure Description

A sewage discharge connector 9 connected to the interior is fixed to the lower end of the left side surface of the pump station body 1.

[0022] The main body 1 of the pump station and the top cover 2 are detachable;

[0023] A valve can be installed between water outlet connector 4 and water pipe 7;

[0024] A valve can also be installed on the left end of the drain connector 9;

[0025] The water outlet connector 4 is higher than the sewage outlet connector 9.

[0026] exist Figures 1-3In the middle section: A transparent window 10 is fixedly connected to the lower end of the front surface of the main body 1 of the pump station. A cleaning mechanism 11 is jointly provided inside the main body 1 and on the upper surface of the top cover 2. The cleaning mechanism 11 includes a motor 12, which is fixedly connected to the upper surface of the top cover 2. A connecting rod 13 is fixedly connected to the output end of the motor 12. A connecting plate 14 is fixedly connected to the lower end of the connecting rod 13. A motor 15 is fixedly connected to the left end of the upper surface of the connecting plate 14. A threaded rod 16 is fixedly connected to the output end of the motor 15. A connecting plate 17 is threadedly connected to the outside of the threaded rod 16. A limiting rod 18 is movably connected through the inside of the connecting plate 17 to the right side of the threaded rod 16. The upper end of the limiting rod 18 is fixedly connected to the lower surface of the connecting plate 14. A limit rod 18 is fixedly connected to the right end of the lower surface of the connecting plate 17. The axes of connecting rod 19, connecting rod 13, and connecting rod 19 are on the same vertical line. A cleaning component 20 is provided at the lower end of connecting rod 19. The cleaning component 20 includes a brush 21. The lower end of connecting rod 19 is fixed to the left end of the upper surface of brush 21. Brush 21 is movably attached to the lower inner surface of pump station body 1. A slider 22 is fixed to the upper surface of brush 21. Slide rods 23 are movably connected to the upper and lower sides of the slider 22. A scraper 24 is fixed to the right end of the two slide rods 23. The scraper 24 is movably attached to the inner side of pump station body 1. A spring 25 is movably sleeved between slider 22 and scraper 24 on the outside of the upper slide rod 23. One end of spring 25 is fixed to slider 22, and the other end of spring 25 is fixed to scraper 24.

[0027] The transparent window 10 faces the cleaning component 20, making it easy to observe the working status of the cleaning component 20;

[0028] Motor 12 is used to drive the cleaning component 20 to rotate, so that the brush 21 therein cleans the silt on the bottom surface inside the pump station body 1, and the scraper 24 therein cleans the silt on the bottom periphery inside the pump station body 1.

[0029] The brush 21 includes a plate and brush bristles fixed to the plate;

[0030] Motor 2 15 is connected to the forward and reverse circuit and has a brake, meaning that the motor shaft cannot rotate after power is cut off; Motor 2 15 is preferably a stepper motor or a servo motor.

[0031] Motor 2 (15) is higher than the water level in pump station main body 1;

[0032] The rotation of the threaded rod 16 can drive the connecting plate 2 17 to rise and fall. After the brush 21 wears out after a period of use (observed through the transparent window 10), the threaded rod 16 drives the connecting plate 2 17 to fall, so that the brush 21 always contacts the inner bottom surface of the pump station body 1.

[0033] The spring 25 is in a compressed state, which makes the scraper 24 always fit against the inner bottom periphery of the pump station body 1.

[0034] The working principle of this utility model is as follows: Water enters the pump station body 1 through the inlet connector 3 and is stored therein. The water pump 6 of the conveying mechanism 5 draws clean water from the outlet connector 4 through the water pipe 1 7 and outputs it through the water pipe 2 8. When sewage needs to be discharged, the motor 12 of the cleaning mechanism 11 drives the connecting rod 13 and the cleaning component 20 to rotate, so that the brush 21 cleans the silt on the bottom surface of the pump station body 1. The scraper 24 is in close contact with the inner wall for cleaning under the action of the spring 25. The sewage is discharged through the sewage connector 9. The staff can observe the condition of the brush 21 and the scraper 24 through the transparent window 10. When the brush 21 is worn to the point that it no longer fits the bottom surface of the pump station body 1, the motor 2 15 is turned on to drive the threaded rod 16 to adjust the height of the connecting plate 2 17, which drives the connecting rod 2 19 to press down the brush 21 to compensate for the wear, so that the brush 21 can always fit the bottom surface of the pump station body 1.
